SB 1384 amends Section 1001 of the California Public Utilities Code to add an explicit exemption: the extension, expansion, upgrade, or other modification of an existing electrical transmission facility — including transmission lines and substations — no longer requires the certificate of public convenience and necessity that Section 1001 otherwise demands. The bill leaves the statute’s existing list of covered corporations and other, preexisting local-extension exemptions intact and preserves the Public Utilities Commission’s power to resolve interference disputes between utilities.
This matters for utility compliance and project planning: the statutory change removes a statutory prerequisite that has been used as a state-level regulatory gate for constructing major transmission elements. Utilities and project developers could avoid a formal PUC certificate process for many transmission upgrades, tightening timelines but also creating new questions about where review and dispute resolution will occur and which approvals still apply.
At a Glance
What It Does
SB 1384 inserts a new subsection into Section 1001 that exempts ‘‘extension, expansion, upgrade, or other modification’’ of existing electrical transmission facilities — explicitly naming transmission lines and substations — from the certificate requirement. It leaves intact the rest of Section 1001, including the covered list of utility types and the PUC’s authority to adjudicate interference complaints.
Who It Affects
Investor-owned electric utilities and their engineering and construction contractors are the primary direct subjects; transmission project developers, regional grid operators (e.g., CAISO), the California Public Utilities Commission, and local permitting authorities are also affected. Environmental reviewers and parties who use the certificate process to surface community concerns will see the biggest procedural shift.
Why It Matters
The amendment removes a statutory chokepoint that could speed delivery of transmission upgrades needed for reliability and decarbonization, but it reallocates oversight: projects that once passed through a PUC certificate hearing may now proceed under other regulatory regimes (local permits, CEQA, interconnection processes), raising questions about notice, public participation, and how costs and siting conflicts are resolved.

What This Bill Actually Does
Section 1001 has long required certain utilities to obtain a certificate from the California Public Utilities Commission before beginning construction of a new street railroad, line, plant, or system. SB 1384 keeps that baseline intact for the classes of corporations listed in the statute but adds a focused carve-out for work on existing electrical transmission facilities.
The new language says that extensions, expansions, upgrades, or ‘‘other modification’’ of an existing transmission facility — explicitly including transmission lines and substations — do not trigger the Section 1001 certificate requirement.
Practically, that means many projects that involve rebuilding, upgrading capacity, reconductoring, adding circuits, or modifying substations could proceed without seeking the PUC certificate that historically served as a state-level permitting step. The bill does not create new procedural steps, thresholds, or notice obligations tied to this exemption; it simply removes the statutory certificate trigger for those activities.
The statute still lists the same set of corporations covered by Section 1001’s construction prohibition, and the longstanding carve-outs for intra-city extensions and contiguous territory remain in place.SB 1384 also preserves the PUC’s role where one utility’s construction interferes with another’s operations: Section 1001(c) remains operative and authorizes the commission, on complaint, to hold a hearing and prescribe terms and conditions to resolve conflicts. The bill therefore shifts the PUC’s posture from pre-construction gatekeeper for certain transmission work to a reactive adjudicator for interference or disputes unless other statutes impose affirmative review requirements.Because the bill is focused and silent about interactions with CEQA, local land-use approvals, FERC jurisdiction in interstate matters, or CPUC cost-recovery and rate-making rules, it creates an implementation landscape where those existing regimes will determine project-level review and remedies.
Compliance officers should not assume that the exemption eliminates other permits or environmental review; instead, it removes one specific statutory certificate requirement and leaves the rest of the regulatory mosaic unchanged and potentially the locus for new disputes.
The Five Things You Need to Know
SB 1384 amends Section 1001 of the Public Utilities Code by adding subsection (b) that exempts ‘‘extension, expansion, upgrade, or other modification’’ of existing electrical transmission facilities — expressly including transmission lines and substations — from needing a Section 1001 certificate.
Section 1001(a) continues to prohibit starting construction of a street railroad, line, plant, or system by the statute’s listed corporations without a PUC certificate; the list of covered corporate types (railroad, street railroad, gas, electrical, telegraph, telephone, water, sewer) remains unchanged.
Section 1001(c) remains in force: the statute still does not require a certificate for certain intra-city or contiguous-territory extensions and authorizes the commission, on complaint and after hearing, to issue orders and prescribe terms where one utility’s construction interferes with another’s operations.
The bill supplies no definitions, thresholds, or procedural mechanics for what counts as an ‘‘upgrade’’ or ‘‘other modification,’’ leaving the scope of the exemption unspecified and subject to administrative interpretation or litigation.
The statutory text includes a drafting anomaly at the end of subsection (c) — an apparent duplication or misplaced phrase — that could create interpretive questions about the precise scope of the commission’s remedial language.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Baseline certificate requirement and covered utilities
Subsection (a) preserves the statute’s core prohibition against beginning construction of a street railroad, line, plant, or system without a PUC certificate when done by the enumerated utility types. For practitioners, this means projects that create new transmission facilities or wholly new lines (as opposed to changes to existing facilities) will still fall squarely under the traditional certificate regime unless another statutory exemption applies.
New exemption for modifications to existing transmission facilities
This newly inserted subsection states that ‘‘extension, expansion, upgrade, or other modification’’ of an existing electrical transmission facility, including transmission lines and substations, does not require a Section 1001 certificate. The practical effect is to remove a statutory precondition for many transmission rehabilitation or capacity projects; however, the provision does not prescribe procedural steps (notice, filings, or classification thresholds) that would guide utility action or agency oversight.
Existing local-extension exemptions and commission dispute power retained
Subsection (c) keeps the statute’s prior carve-outs for extensions within a city or into contiguous territory not served by a similar utility, and for extensions necessary in the ordinary course of business within already-served territory. It also preserves the commission’s complaint-driven authority to hold hearings and establish terms and conditions if a utility’s construction interferes with another utility or public water system. That preserves a reactive enforcement mechanism even as proactive certificate review for many transmission modifications is removed.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Investor-owned electric utilities (e.g., utilities that own transmission lines): The exemption reduces the need to secure a Section 1001 certificate for many upgrade projects, shortening preparatory timelines and lowering transactional overhead for routine and some substantial transmission work.
- Transmission project developers and contractors: Fewer certificate hearings can reduce schedule uncertainty and contracting risk associated with PUC adjudication timelines.
- Grid operators and planning entities (e.g., CAISO): Faster implementation of reliability or congestion relief upgrades can improve the operator’s ability to address system needs identified in planning processes.
- Utilities’ operations and engineering teams: The change gives engineering-driven choices more direct paths to construction where work is confined to existing facilities, simplifying project management.
Who Bears the Cost
- California Public Utilities Commission: The PUC loses a proactive statutory gate for many transmission changes, shifting its role toward complaint-driven dispute resolution and potentially increasing reactive adjudication workload without a parallel increase in resources.
- Local governments and affected communities: With fewer certificate hearings, local stakeholders may have reduced formal opportunities at the state level to present siting, aesthetic, or safety concerns specific to transmission upgrades.
- Environmental and community groups: The removal of the certificate requirement narrows one procedural avenue to surface environmental or equity objections, pushing those challenges into CEQA or local permitting forums that may be less centralized.
- Competing utilities and public agencies that share corridors: These parties may have to rely on post-construction complaints to the commission rather than having pre-construction conditions set through the Section 1001 process, increasing the risk of operational conflicts.
Key Issues
The Core Tension
The central dilemma SB 1384 creates is between accelerating grid upgrades (to meet reliability and decarbonization goals) and preserving centralized, pre-construction state oversight and public participation. Speed and reduced procedural friction serve system needs and utilities’ project schedules; centralized certificate hearings protect coordinated review, transparency, and pre-construction resolution of conflicts — two legitimate aims that the bill forces into tension without providing a clear mechanism to balance them.
The bill’s narrow textual change raises several practical and interpretive questions. First, the key operative phrases — ‘‘upgrade’’ and ‘‘other modification’’ — are undefined, so the line between a project that needs a certificate and one that does not is unclear.
Without statutory thresholds or guidance, utilities, the PUC, and courts will have to develop tests based on project impact (capacity change, footprint, voltage change) or intent, which could produce litigation and inconsistent outcomes.
Second, SB 1384 does not displace other regulatory regimes. CEQA review, local land-use permits, environmental mitigation obligations, interconnection procedures, and any applicable federal approvals remain in force.
In practice, many substantial transmission projects will still face environmental review and local permitting, which may blunt the intended streamlining. That said, removing the Section 1001 certificate removes a centralized state hearing whose record is often used by stakeholders to surface concerns; moving review into a patchwork of other processes can complicate public participation and coordination.
Finally, the bill potentially changes the timing and locus of disputes. The PUC’s preserved complaint authority is reactive: rather than pre-setting terms at the outset of construction through certificate proceedings, the commission will more often resolve conflicts after projects are underway or completed, which can raise costs and operational risk.
The drafting anomaly in subsection (c) — a duplicated or misplaced phrase — also creates a risk of interpretive litigation unless the Legislature or the commission clarifies intent.
